WIN DOW-WASH ER.

SPECIFICATION forming part of Letters Patent No. 548,892, dated October 29, 1895.

Application led July 22, 1895. Serial No. 556,783. (No model.)

.To all whom it may concern.-

Be it known that l, ELIAS SKINNER, a citizen of the United States, residing at Grand Rapids, in the county of VKent and State of Michigam have invented certain new and useful Improvements in Window-Washers, of which the following is a specification.

My invention relates to improvements in appliances for holding a sponge or cloth for washing and a rubber for wiping a window;`

.show the serrations or teeth that hold the cloth in place; and Fig. 5 is a perspective of the rubber-clamp, showing serrations or teeth for use when the rubber is held in by a spring.

Similar letters refer to similar parts throughout the several views.

In constructing my window-washer I prol vide a head A, which has an arm o, projecting in one direction to form one or the supporting jaw of the rubber-clamp, and another arm a', that stands at an obtuse angle with the first and forms the supporting-jaw of the spongesupporting clamp, and to this head is cast or otherwise attached a socket F for the support or reception of the handle F.

For securely holding the sponge D in my Washer I pivot a jawB to the head A, as at b, and to secure the rubber commonly used for drying a window after it has been washed I provide a detachable jaw C. The spongesupporting clamp is provided with teeth c, so located that they will pierce the sponge alternately, as indicated in Fig. 4, to prevent the possibility of the sponge becoming disengaged, and a similar series of teeth, as c in Fig. 5, though much smaller than those shown at a, may be with advantage placed on -the inner surface of the jaw C that holds the rubber.

To force the jaws B and C solidly toward the arms a and a, I provide a coiled spiral spring E, having a bow e at the center that extends upward against the back surface of the jaw B, and the opposite ends e extend down in the opposite direction and rest on the detachable jaw C, so that the entire concentrated tensile force of the spring is utilized, the oneportion to force the jaw B in place and the other portion to force the jaw C solidly against the arm a, so that both clamps are forced to securely clamp and hold the object that is inserted. The pivot-rod b, by which the jaw B is pivoted to the head, is made to extend the entire length of the head and through the socket and the end of the handle, as indicated in Figs. 2 and 4, and, passing through the coil of the spring E, acts as a support therefor. ,k A

I sometimes find it necessary to provide an auxiliary spring E to insure a perfect bearingof the jaw C on the rubber, and for this purpose I find the most satisfactory spring to be formed, as in Fig. 2, with a loop, as c, passing around one side of the socket F, the body of the spring coiled around the pivotrod b and the ends e? brought to bear upon the jaw a little to each side of its longitudinal center.

I sometimes dispense with the springs tor supporting the jaw C and secure it with screws, as c.

If it is desired to convert this head into a sweeping device for tile ioors, it is simply necessary to distend the jaw B, as indicated in Fig. 4, when a brush may be clamped between it and the arm c in the usual Way in lieu of the sponge, and the object is accomplished.

In Fig. 4 I have cut the spring e o before the coiled portion E is reached, and Fig. 3 shows the arm a. disconnected from the head and the socket F, and is given simply to show how' the jaw C may be secured by the screws o instead of the spring, as more fully described in the preceding portion of this specitication.

Having thus fully describedmy invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a window washer, a head having arms extending at obtusel angles therefrom and a socket to support the handle, a jaw pivoted to the head to connect with one of the arms to secure a sponge, a detachable jaw to com- IOO bine with the other arm to secure the rnbber, a pivot rod passing the entire length of the head and through the ends thereof, the pivot arms of the jaw B, and the socket, a spring coiled around said rod, its center bowed to press against the jaw B and its ends bearing against the detachable jaw O and an auxiliary spring coiled around said rod in position toassst in securing the jaw C, substantially as and for the purpose set forth.

2. In a window washer, a head having a socket for the handle, arms extending in opposite directions from said head, jaws tted to combine with said arms to support, the one a sponge and the other a drying rubber, teeth I 5 projecting inward from said arms and jaws, and a spiral coiled spring and pivot rod to supportY said jaws, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, July 17, 2c 1895.
